Title: Catastrophic error recovery apparatus and associated methods
Inventor: HIER CRAIG ALAN
IPC: B24B37/34
Filed: 1999-10-29
Granted: 2001-09-11
Abstract: An apparatus and method of restoring the position and status information for each of a plurality of workpieces in a workpiece processing system is disclosed. As workpieces are loaded, processed, and unloaded from a workpiece processing system a sensor assembly tracks the location and status of each workpiece. The sensor assembly provides such status and location information to a processor. The processor allows an operator to overwrite or enter new status and location information while also providing such information to a non-volatile storage system. Whenever, the operation of a workpiece processing system is catastrophically interrupted and all previously entered variable erased from the processor, the present invention allows an operator to recall the previously, and periodically updated data from the non-volatile storage system and reset processor parameters. Additionally, the operator may determine which workpiece(s) are salvageable and may resume processing the salvaged workpieces. Additionally, the present invention allows the operator to recall at any time the loaction and status of any workpiece.

Title: Panel assembly for liquid crystal displays
Inventor: VON GUTFELD ROBERT JACOB
IPC: G02F1/13
Filed: 1999-10-29
Granted: 2006-12-21
Abstract: When fabricating a liquid crystal panel from a pair of substrates using the ""one-drop fill"" method to deposit liquid crystal material in a central portion of one substrate and then sealing the substrates together with a fillet of epoxy between the outer peripheral portions of the substrates, the uncured epoxy tends to contaminate the liquid crystal material and impair its function. Here, a relatively thick barrier fillet, as of silicone elastomer, is deposited in the form of a continuous closed circuit upon one of the substrates and is fully cured before depositing the liquid crystal material within that closed circuit. To seal the substrates together, they are brought together to a spacing determined by a relatively thin spacer fillet provided on one of the substrates and an epoxy fillet is deposited along the outer periphery of the substrates. The barrier fillet, preferably compressed, serves to prevent contamination of the liquid crystal material by any regions of uncured epoxy. In one variation, the epoxy fillet is formed from a two-component epoxy by depositing a continuous circuit of one component to surround the barrier fillet on one substrate and depositing an identical continuous circuit of the other component on the other substrate before joining the substrates together to intermix and cause cross-linking of the components to form a cured epoxy fillet.

Abstract: This invention relates to an interconnection structure that includes a routing network used to provide programmable mutual interconnection track for the functional device that is electrically connected to the interconnection structure. This routing network has N connection apparatus, in which N is an integer and is larger than 4. The interconnection structure also includes N switching devices, in which each switching device is electrically connected to one corresponding connection apparatus and is selectively electrically connected with at least one function device. Each switching device is used to make the output/input terminals of the function device, which is connected with the switching device, have programmable connection with the corresponding connection device. The interconnection structure provided in this invention is executed in an electronic circuit system, in which the arbitrary output/input terminal of one function device for this system can be interconnected to the arbitrary output/input terminal of the other function device. During the design and fabrication of this system, the total number of programmable switch for substantially executing track change in interconnection structure is obviously decreased as compared with total number of programmable switch required for previous technique. Therefore, the execution performance and integration of this system are all apparently improved such that the production cost can also be greatly reduced.

Title: Manufacturing method to form air gap using hardmask to improve isolation effect
Inventor: LI JENG-HUNG
IPC: H01L21/768
Filed: 1999-12-20
Granted: 2001-06-07
Abstract: This invention describes a manufacturing method to form air gap by using hardmask. Patterned hardmask is firstly produced on the semiconductor substrate and high aspect ratio openings are formed on the dielectric layer by utilizing the etching selectivity between the hardmask and the dielectric layer. Subsequently conductive plugs are deposited into the openings, hardmask is removed and a layer of silicon oxide with low step coverage is deposited. The isolation effect can be enhanced due to the air gap formed between conductive layer and dielectric layer after the hardmask removal.

IPC: G02B6/34
Filed: 2000-01-25
Granted: 2001-01-21
Abstract: Disclosed is a fiber optic filter that includes a central core, a ring core concentric with the central core, an inner cladding region of refractive index ni between the central and ring cores, and a cladding layer of refractive index nc surrounding the ring core. The maximum refractive index n1 of the central core and the maximum refractive index n2 of the ring core are greater then nc and ni. The propagation constants of one core mode and one ring mode are different at wavelengths except for at least one wavelength <lambda>o whereby power transfers between the two cores at <lambda>o. At least a portion of the fiber optic filter fiber is wound around a reel to subject it to a continuous curvature, the radius of which determines the amplitude of the attenuation. Such fibers are useful in fiber amplifiers in which the central core contains active dopant ions.

Title: Gas phase alkylation-liquid phase transalkylation process
Inventor: GHOSH ASHIM KUMAR
IPC: C07C15/073
Filed: 2000-03-14
Granted: 2003-03-21
Abstract: Process for the production of ethylbenzene by alkylation over a silicalite alkylation catalyst with the subsequent transalkylation of diethylbenzene with the alkylation catalyst and conditions selected to retard xylene production and also heavies production. A feedstock containing benzene and ethylene is applied to a multi-stage alkylation reaction zone having a plurality of series-connected catalyst beds containing a pentasil molecular sieve alkylation catalyst which is silicalite of a predominantly monoclinic symmetry having a silica/alumina ratio of at least 275. The feedstock is supplied to the alkylation reaction zone to cause gas-phase ethylation of benzene at a flow rate to provide a space velocity of benzene over the catalyst to produce a xylene concentration in the product of about 600 ppm or less based upon the ethylbenzene content. Periodically the space velocity may be increased to a value which is greater than the space velocity associated with a minimum concentration of diethylbenzene in the alkylation product such that diethylbenzene production is enhanced while minimizing any attendant transalkylation reactions within the alkylation reaction zone. This is accompanied by a relatively low xylene content in the product, specifically no more than 600 ppm based upon the ethylbenzene in the product. The output from the alkylation reactor is applied to an intermediate recovery zone for the separation and recovery of ethylbenzene with the recovery of a polyalkylated aromatic component which is supplied along with benzene to a transalkylation reaction zone where the polyalkylated aromatic fraction is subject to disproportionation to provide a reduced diethylbenzene content and an enhanced ethylbenzene content. A specific monoclinic silicalite alkylation catalyst has a silica/alumina ratio of at least 300 and has a crystal size of less than one micron.
